To all whont it'ntasy concern.-

ng Sun, in the county of Ohio and State of ful Improvements in Mechanism for Vinding Perforate SheetMusic,-of which the following is a specification.

The present invention embodies improvements in mechanical musical instruments of Indiana, have invented certain newandusethe self-playing type which utilize a perforate I music strip or sheet and winding mechanism 1 therefor.

The invention resides particularly in the.

operating means provided for winding and unwinding the music-strip with regardto the rolls commonly provided tosup'p ort the same. For a full description of the invention and the merits thereof and also to acquire aknowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

WVhile the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features 1 thereof, still the preferred embodiment is l shown in the accompanying drawings, in which Figure 1 is a perspective view of a winding mechanism for perforate sheetmusic embodying the invention. view thereof. Fig. 3 is a transverse section on the line 90 cc of Fig. 2. Fig. 4 is a detail perspective view of the shipper-lever and. parts moved tl' ereby. Fig. 5 is a view at the left-hand end. of the mechanism. Fig. 6 is a detail perspective view of an end portion of the tracker-bar, showing the guide and adjusting means. Fig. 7 is a detail section showing the means for longitudinally adjustto in the following description and indicated in all the views of the drawings by the same reference characters.

The component parts of the mechanism may have anyrelative arrangement and be mounted in a framework of suitable construction, depending upon the character of the instrument to which the invention is adapted. The unwinding-roll is indicated 1, the nuil sic-roll at 2, and the tracker-bar at 3. These j parts may be of any construction andusual 1 Be it known that 1, JOHN w. wmttoek, a i' citizen of the United States, residing at Risl Fig. .2 is a front} arrangement and are mounted iii a framework comprising parallel bars 4 and Sand connecting-bars 6 and 7. One journal of the unwinding roll is provided with a gear-wheel 8, and the opposite journal hasa set-screw 9 connected therewith, whereby said roll maybe adjusted lengthwise to meet existing condltlOIlS, a jam-nut 10 serving to hold the set-screw and roll '1 in the adjusted position. The trackerbar8 is adapted to be moved longitudinally in accordance with this invention and is directed in'its movements by guide-pins 11, secured to opposite ends thereof'and arranged to workin openings formed in the frame-bars 4 and 5. A setscrew'12, threaded into the bar 4, has en.- gagement with the tracker-bar to effect positive shifting thereof, as maybe required, a jam-nut 13, mounted upon said set-screw, holding it and the tracker-bar in the located position.

The music-roll 2 is provided with the per Patented Dec. 1 1, 1906.;

forate music sheet 14, which in the operation J of the instrument passes over the tracker-bar 3 and is wound upon the roll 1. The musicroll 2 is supported at its ends by means of the pring-actuated pin 15 and the journal 16,

s the latter interlocking with the roll 2 to ef' feet a positive turning thereof when it is required to rewind the music-sheet thereon; A pinion 17 is loosely mounted upon the journal 16, and a drive-chain 18 or like means connects said pinion with a gear-wheel 19,

chain, the elements 17 and 19 will be pro.

vided with corresponding sprockets or teeth to make ositive cnga emcnt withthe links p i. '3 z of the chain. A half-clutch 21 is mounted upon the ouinal 16 to turn therewith and to ,move toward an Hi from the element 17, which latter is provided'upon the face adjacent to the part 21 with a corresponding half-clutch, Ico

whereby upon interlocking of the two halfclutches the parts 17, 21, and 16 rotate in unison, so as to effect a turning of the roll 2 when it is required to rewind the nmsic-sheet 1a thereon.

A shaft 22 is mounted in the bar 5 and in a companion bar23 to have both a rotary and a longitudinal movement and has a pinion 24 fast therewith and adapted to be thrown into and out of gear with the teeth of the no within the path of an operating-lever 28, moved at proper intervals of' the instrument, a suitable trip mechanism shaft 22 by means Having thus described the invention, what is claimed as new is-- 1. In winding mechanism for perforate gear-wheel 8'. A shipper-lever 25,- pivotally supported at a point between its ends, has positive engagement at opposite ends with, respectively, a collar 26,fast with shaft 22, and the half-clutch 21. Adiarm 27 projects from the shipper-lever 25 and extends roll, anunwinding roll, a journal for the nu sie-roll, 'a drive-shaft, agear 8 fast to the unwinding roll, a longitudinally movable pinionshaft adjacent to said gear, a pinion 24 fast to said pinion-shaft and movable longitudinally therewith into and out of mesh with the gear 8, connecting'means between the drive and pinion shafts to effect simultaneous operation thereof, a clutch mounted on the journal of the music-roll and having a member fast thereto, connecting means between the loose clutch member and the driveshaft, and a shipper-lever operatively connected with the pinion-shaft to effect longitudinal movement thereof and intermeshing of the gear 8 and pinion 24, and said shipperlever being connected with the said loose clutch member. I v

- 2.. In win-ding mechanism for perforate sheet-music, the comb'nation of an unwinding-roll, a music-roll, a gear 8 fixed for rotation with the unwinding-roll, a pinion-shaft adapted to receive both a rotaryand a longitudinal movement, a pinion 24 fast to said shaft'and longitudinally movable therewith into and out of mesh 'with the gear 8, a clutch mounted on a journal of the music-roll and having one member loose, sprocket chain connecting y the mechanism ofthe instrument embodying the 'invention.. A. spro'cketchain 29 or like connection transmits motion from the shaft 20 tothe of sprocket-wheels 30 and 31, fast to the said respective shafts. In practice the shaft 20 is continuously. driven romthe moving part of the operating mechanism in any convenient way, as by means of ,a drive-belt (not shown) passing around a cone-pulley 32, fast to the outer endof shaft 20'. The, motion imparted to shaft 20 is transmitted to eachof the sprocket-chains 18 and 2.9 and to the parts 17 and 31. In one position of the ship er-lever 25 the part 21 is in clutched engagement with the parts 17, thereby causing shaft 16 to rotate,.and the shaft 22 is moved so as to disengage the pinion 24 from the gear-wheel 8v. Rotation of journals 16 causes a-corresponding'movement of the roll 2, whereby the music-sheet is unwound from roll 1 and wound upon the said roll 2'. When the shipper-lever 25- is moved to the other position, the pinion 24 is in meshing relation with the gear-wheel 8 and the part 21 is disengaged with the part 17. Hence movementis imparted onlyto theunwinding-roll 1, said movement being comparatively slow by reason of the differences in the diameters of the parts 8 and 24 and 31 and 30. When the unwinding-roll is thrown out of action and the roll 2 is thrown into gear, the speed of said roll 2 is comparatively high by reason of'the large diameter of the art 19 and the small diameter of the part 17. ence the music-sheet is rewound upon the roll 2 rapidly It is proposed to actuate the shipper member 25 automatically from a convenient portion of the actuating mechanism the drive shaft chain connecting the drive-shaft with the loose clutch member, and a shipper-lever pivoted between its ends, one end of the shipper-lever having connection with the loose clutch member and the opposite end having connection with thepinion-shaft to effect unmeshing of the pinion 24 and the gear Ssimultaneously with the meshing of thetwo clutch members.

In testimony whereof I affix my signature in presence of two'witnesses.
